Symptom(s)

The drying cycle stops before completion and the control panel displays the F3E3 error code.

Possible Cause(s)

The F3E3 error can be caused by any of the following conditions:

  • Open or shorted inlet thermistor
  • Poor electrical connection at the ACU or loose inlet thermistor wire at connector J14
  • Blocked or restricted exhaust vent limiting airflow
  • Failed ACU and console assembly when all other causes have been ruled out

Safety Warning

WARNING Electrical Shock Hazard Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock.

Diagnostic Procedure

Work through these checks in sequence for accurate diagnosis:

  1. Disconnect power to the dryer at the circuit breaker or unplug the unit.
  2. Test the inlet thermistor for an open circuit or short. Refer to the model-specific service manual, for resistance specifications and test points.
  3. Inspect all wiring and connectors at the ACU. Confirm the inlet thermistor wire is fully seated in the J14 connector with no loose terminals, corrosion, or damaged wires.
  4. Check the complete exhaust vent path from the dryer outlet to the exterior termination for lint buildup, kinks, crushed sections, or excessive length. Clean or correct any restrictions to restore proper airflow.
  5. If the F3E3 error remains after the thermistor, wiring, and vent checks, the ACU and console assembly requires replacement.

Recommended Repair

Perform the repair that matches your diagnostic findings:

  • Replace a defective inlet thermistor using the correct part number for the model.
    • Follow the service manual removal and installation steps.
    • Clear codes and run a test cycle to confirm resolution.
  • Secure any loose connections at the ACU and ensure the J14 connector is fully engaged.
    • Reassemble the dryer, restore power, and verify normal operation through a complete cycle.
  • Clear all blockages from the vent system.
    • Recommend regular vent maintenance to the customer to prevent repeat issues.

When the error continues after the thermistor, connection, and vent steps have been completed:

  • Order and install the exact ACU and console assembly service kit listed for the model above.
    • Follow the instructions supplied with the kit for wiring and mounting.
    • Replace all panels before restoring power.
    • Run multiple test cycles to confirm the F3E3 error no longer appears.
